Recording/playback apparatus and power control method

Abstract

This invention provides a recording/playback apparatus comprising a first unit which performs recording/playback processing of video data, a second unit which communicates with a terminal, and a control section for independently controlling power supplied to the first unit and power supplied to the second unit.

What is claimed is:  
     
         1 . A recording/playback apparatus comprising: 
 a first unit which performs recording/playback processing of video data;    a second unit which communicates with a terminal; and    a controller independently controlling power supplied to the first unit and power supplied to the second unit.    
     
     
         2 . An apparatus according to  claim 1 , wherein the controller supplies power to only the second unit when the first unit is not used.  
     
     
         3 . An apparatus according to  claim 1 , wherein the controller supplies power to the first unit upon reception of a command indicating use of the first unit from the terminal, and shuts off power supplied to the first unit upon reception of a command indicating inhibition of use of the first unit.  
     
     
         4 . A power control method in a recording/playback apparatus including a first unit which performs recording/playback processing of video data, and a second unit which communicates with a terminal, comprising: 
 determining whether a first command indicating use of the first unit is received from the terminal;    supplying power to the first unit when determining that the first command is received;    determining whether a second command indicating inhibition of use of the first unit is received; and    shutting off power supplied to the first unit when determining that the second command is received.    
     
     
         5 . A method according to  claim 4 , further comprising steps of: 
 determining whether a third command indicating inhibition of use of the second unit is received, and    shutting off power supplied to the second unit when determining that the third command is received.
